Long‐term apparent survival of a cold‐stunned subpopulation of juvenile green turtles

open access: yesEcosphere, 2022
Understanding the effects of extreme weather on animal populations is fundamental to ecological and conservation sciences and species management. Climate change has resulted in both warm and cold temperature extremes, including an increased frequency of ...

Post-epizootic salamander persistence in a disease-free refugium suggests poor dispersal ability of Batrachochytrium salamandrivorans [PDF]

open access: yes, 2018
Lack of disease spill-over between adjacent populations has been associated with habitat fragmentation and the absence of population connectivity. We here present a case which describes the absence of the spill-over of the chytrid fungus Batrachochytrium

On the Assessment of Sinking Particle Fluxes From In Situ Particle Size Distributions

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The biological carbon pump is a vital component of the global carbon cycle, particularly through the sinking of particulate organic carbon (POC) into the ocean interior. Particle size distribution (PSD) observations from the Underwater Vision Profiler (UVP) have been widely used to quantify sinking POC fluxes.

The average laboratory samples a population of 7,300 Amazon Mechanical Turk workers [PDF]

open access: yes, 2015
Using capture-recapture analysis we estimate the effective size of the active Amazon Mechanical Turk (MTurk) population that a typical laboratory can access to be about 7,300 workers.

Multi‐event modeling of Hector's dolphin (Cephalorhynchus hectori) fecundity using four decades of monitoring: Implications for current management of bycatch

open access: yesConservation Science and Practice, Volume 8, Issue 4, April 2026.
Updated estimate of fecundity for Hector's dolphin is lower and more precise than prior estimation. This latest estimate suggests a lower capacity for population growth than previously thought and a reduced resilience to anthropogenic threats. Abstract Prediction of future population trajectories is vital in the management of threatened species but ...

Modelos jerárquicos de marcaje–recaptura: un marco para la inferencia de procesos demográficos [PDF]

open access: yes, 2004
The development of sophisticated mark–recapture models over the last four decades has provided fundamental tools for the study of wildlife populations, allowing reliable inference about population sizes and demographic rates based on clearly formulated ...

Distance of movement in three threatened butterfly species

open access: yesEcological Entomology, Volume 51, Issue 2, Page 250-260, April 2026.
Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

Photo-identification and its application to gregarious delphinids: Common dolphins (Delphinus sp.) in the Hauraki Gulf, New Zealand : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Ecology at Massey University, Albany, New Zealand [PDF]

open access: yes, 2016
Common dolphins (Delphinus sp.) remain one of the most poorly understood delphinids within New Zealand waters. Baseline data on their abundance, site fidelity, movement patterns, and social structure remain unknown.

Population Demographics of Killer Whales (Orcinus orca) in Western Australia

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer
